Abstract
Maternal-placental perfusion can be temporarily compromised by Braxton Hicks (BH) uterine contractions. Although prior studies have employed T2* changes to investigate the effect of BH contractions on placental oxygen, the effect of these contractions on the fetus has not been fully characterized. We investigated the effect of BH contractions on quantitative fetal organ T2* across gestation together with the birth information. We observed a slight but significant decrease in fetal brain and liver T2* during contractions.
摘要
母体-胎盘灌注可因布拉克斯顿·希克斯（Braxton Hicks，BH）子宫收缩而暂时受到影响。尽管先前的研究已经采用 T2变化来研究 BH 收缩对胎盘氧合的影响，但这些收缩对胎儿的影响尚未得到充分描述。我们研究了 BH 收缩对整个孕期胎儿定量器官 T2的影响，以及出生信息。我们观察到胎儿大脑和肝脏 T2*在收缩期间略有但显著降低。
